英国最古老，最大的专家彩色玻璃保护工作室最近在约克大教堂的大东窗户的保护下，在这里的帮助下卡尔·蔡司显微镜。
The York Glaziers Trust chose a pair of Stemi DV4 Spot microscopes to investigate surface corrosion on Britain's largest expanse of medieval stained glass and the Zeiss AxioCam to record the phenomena for future reference.

根据约克·格拉泽尔（York Glaziers）信托基金会主任兼染色玻璃保护硕士课程主任莎拉·布朗（Sarah Brown）的说法，“每个小组的保守前检查和文档都需要长时间的显微镜和两个新获得的STEMI DV4 SPOT显微镜现在是我们研讨会中保护器工具包的重要组成部分。这些显微镜的出色光学和出色的构建质量是任务的理想选择。STEMIDV4斑点是一种乐趣，可以在大型上进行精确调整。但是面板易于努力。”
在初步摄影和文档之后，每个面板都会拆除，以清洁和修复单个玻璃碎片的表面。通过显微镜进行监测对于确保基本玻璃的细腻保护凝胶层或潜在易受伤害的油漆层均未因清洁过程而损坏。完全拆卸还可以使原始玻璃件的边缘键入在重新融化之前恢复受损的碎片。
莎拉说：“ STEMI DV4在研究腐蚀的玻璃表面上也非常宝贵，我们才刚刚开始欣赏它们的全部潜力。”“强化眼镜，尤其是窗户中使用的'闪光'红色红色，特别容易受到腐蚀的影响，显微镜使信任能够记录独特的和特征性的腐蚀现象，以供将来参考。几个故意磨碎的红宝石玻璃被发现如此如此的例子。到目前为止，人们特别感兴趣。”
The Minster's Great East Window was commissioned in 1405 from the Coventry glazier, John Thornton, and upon completion in 1408, depicted the beginning and the end of all things. Under a figure of God holding a book with the words 'Ego sum alpha et omega' (I am the beginning and the end), the main lights tell the story of Creation and the events of the Apocalypse. With funding from the Heritage Lottery Fund, the complete restoration of the window and its return with state-of-the-art environmental protection will be completed in 2016. The project will ensure its preservation in close to museum conditions for many generations to come and was the subject of BBC4's recent documentary, 'Britain's Most Fragile Treasure'.
With a 4:1 zoom range and a 92mm working distance, the Stemi DV4's best-in-class, parfocal zoom optics enable distortion-free imaging over the whole of the large object field. Digital and video cameras may be rapidly connected for image capture and recording and the system is also fully-compatible with Zeiss AxioVision imaging and archival software. Other options available for the Zeiss Stemi DV4 Stereomicroscope include transmitted-light darkfield equipment, eyepiece measuring devices, and attachment systems that enable enhanced resolution magnification up to 64x.
